Abstract (English):	Introduction: distal biceps tendon rupture is an uncommon injury, with an incidence of two to three cases per 100,000 people annually. It predominantly affects men between the ages of 40 and 60, commonly in the dominant arm and during eccentric contractions. Surgical treatment is preferred as it allows better restoration of supination and flexion strength. Proper anatomical positioning has been shown to optimize forearm supination strength. Clinical case: a 45-year-old male developed an injury to the posterior interosseous nerve secondary to improper positioning of the distal biceps tendon during reinsertion. A revision surgery was performed. Conclusion: this case provides clinical evidence of a specific complication rarely described: posterior interosseous nerve entrapment due to incorrect tendon reinsertion. The value of proper anatomical positioning to avoid neurological sequelae is emphasized, as well as the importance of timely surgical reintervention to restore function. [ABSTRACT FROM AUTHOR]
Abstract (Spanish):	Introducción: la ruptura del tendón distal del bíceps es una lesión infrecuente, con una incidencia de dos a tres personas por cada 100,000 personas al año, que afecta principalmente a hombres entre los 40 y 60 años, comúnmente en el brazo dominante y durante contracciones excéntricas. El tratamiento quirúrgico es preferido, ya que permite restaurar mejor la supinación y fuerza de flexión. Se ha demostrado que el posicionamiento anatómico adecuado optimiza la fuerza en la supinación del antebrazo. Caso clínico: hombre de 45 años que desarrolló una lesión del nervio interóseo posterior secundario a un posicionamiento inadecuado del tendón distal del bíceps derecho en su reinserción, por lo cual se le somete a una cirugía de revisión. Se documenta la evolución clínica, el tratamiento quirúrgico de reintervención y el seguimiento. Conclusión: este caso aporta evidencia clínica sobre una complicación específica poco descrita: el atrapamiento del nervio interóseo posterior debido a una reinserción incorrecta del tendón. Se enfatiza el valor de realizar un posicionamiento anatómico adecuado para evitar secuelas neurológicas, así como la importancia de la reintervención quirúrgica oportuna para restaurar la función.
